It's most likely the "main relay". A major honda/acura problem. The
main relay cuts off the fuel pump which stops fuel from getting to the
engine. If you spray staring fluid into the intake, you are spraying
fuel for starting direct into the engine. You definitely need the "main
relay" in this case. In my opinion, you can find it cheaper than $45.
Look around!

The dealer doesn't know.

Older traditional combined PGM-FI Main Relays did not "overheat", but
suffered from cracked solder. Letting the Relay cool down would
sometimes re-establish sufficient contact between the cracked parts to
allow starting.

Probably coincidence, in this case.

Very important questions: When the key is first turned to "II", does the
MIL illuminate for 15-20 seconds, then go off and stay off? And does it
remain off after the car is started? Or is it on all the time?

I think Honda uses the PGM-FI Main Relay for that purpose: Engine
stalls, fuel pump and injectors shut off. The engine must be turning for
the ECM to allow the fuel-pump and injectors to operate.

If your model is one of those new enough to have the traditional single
PGM-FI Main Relay split into two (which I'm not sure it is), then you
have one relay for the injectors and one for the fuel pump. They are
always installed together, in my limited late-model experience. And the
split kind are utterly reliable.
